Amid a desolate zombie apocalypse, an unusual female infected retains her human memories and innocent temperament despite possessing no pulse and sluggish reflexes. Longing to reunite with her lost sister, she wanders into the wastelands and accidentally blunders into a squad of seasoned human survivors. Through a series of bizarre lucky coincidences, her clumsy movements neutralize mutant monsters, convincing the team that she is a reclusive martial arts master.
The squad's brooding captain, famous for his ruthless hatred of all undead creatures, becomes deeply infatuated with her gentle silence and enigmatic composure. As they travel toward the primary human sanctuary, she must conceal her cold skin and nonexistent heartbeat while navigating hazardous mutant swarms. One minor medical inspection could blow her cover and turn the man she cares for into her executioner.
